The chairman of the Arizona Republican Party and two other Arizona members of the Electoral College on Monday questioned President Barack Obama's birth certificate during the formal casting of the state's electoral votes.

Arizona GOP Chairman Tom Morrissey said during the state's Electoral College meeting that Obama did not produce a "legitimate" birth certificate, KNAU reports. Morrissey's comments came as presidential electors nationwide formally elected Obama over Republican Mitt Romney.

"I'm not satisfied with what I've seen," Morrissey said during the meeting. "I think for somebody in the president's position to not have produced a document that looks more legitimate, I have a problem with that."

Morrissey was joined in doubting Obama's citizenship by two other Arizona electors, Gila County Republican Party Chairman Don Ascoli and former Graham County Republican Chairman John D. Rhodes, the Associated Press reports. Ascoli questioned whether Obama had been"properly vetted as a legitimate candidate for president."
